lights. orhead lights such as are particularly. used on automobiles and road vehicles to light up the path ahead.

These lamps, which are usually of the acetylene type or of the electric type, give such a powerful beam that the glare is blinding to pedestrians or othersgetting in the range of the same. 011 this account several large cities and some States have passed laws and regulotions, requiring the lights to be dimmed or wholly extinguished Within the city limits. This is inconvenient, as a rule, with the lamps as now usually constructed and when the lamps are Wholly extinguished they become useless for road lighting purposes.

It is therefore one of the principal objects of our invention to provide means whereby the light beam may be partially or wholly intercepted and shaded at. the will of the operator, and to that end the invention propermitting the remainder of the same to shine forth in its full intensity, in order that that portion of the light above the horizontal plane, which would blind a pedestrian, may be shaded without interferwith the part used to light the road ahead.

" More subordinatelythe invention includes those novel details of construction, combination and arrangement of parts all of which will be first fully described, and

y then be specifically pointed out in the 55.9-- pen'ded claims, reference being had to the accompanying drawings, in which Figure l is a perspective view illustrating one form of the invention, in which the shield has been let down half Way. Fig. 2 is a vertical longitudinal-section of the in- 'vention, with the parts in the position shownin Fig. 1. Fig. 3 is an enlarged d 5- tail sectional view showing the position of the parts telescoped into the chamber body, as they normally he. Fig. 4: is an enlarged detail view showing one way of holding the colored glass or other more or less opaque body in the, skeleton frames. Fig. 5 is a detail perspective view showing the action of the spring. Fig. 6 is a detail section and plan of the same. 7 is a perspective view similar to Fig. 1, showing the shield in its closed position to completely inter:- cept the light beam. Fig. 8 is a view similar to Fig.9 of the parts in the position shown in Fig. '7. Fig. 9 is a detail perspective view of the'chambered body, a portion being broken away for convenience of illustration. Figs. 10 and 11 arelongitudinal vertical sections oi' modifi d forms of the inyention. 1

Referring now to the drawings in which like figures andletters' of reference designate like parts in all of the figures, 1 repre sents the lamp, which may be of any type desired, either gas, electric, or oil, etc.

2 is the usual'door oi the lamp and in applying our invention to the lamps now in common use on automobiles and the like, we-

:orovide a chambered body 3, having its lower half beveled as 4 downwardly and outwardly from the horizontal pivotal axis.

The upper half of the chambered body 3 is open at the front as at (5 as best shown in Fig. 9 whereby the shield may be folded up into the upper half of the chambered body as shown in Fig. 3.

The shield, which. we employ in connection with the chambered body 3, is designed to be closedover the front of the lanip to intercept the light beam and it-ma-y be cdn structed of'one or more sections, as found convenient in practice, although we prefer to use a plurality of spherical segments consisting of skeleton frames 8 having stops 9 to limit their extendibility and provided with Windows 14 of a more or less opaque substance such as colored glass, or even a relatively dark body that will entirely out off the light, may be employed. a

In the preferred form shown in Figs. 1 to 9 inclusive, the shield is of the vizorllike type and is composed of a plurality of sphericalsegments 8 as before mentioned. The lower one, of these segments is pro- E r r 1,145,414

- iacent to thediirer and is operated by him skeleton frames 8 haveftheir lwind'ow in any suitable manner. A, spring 1,8 is provided which continuouslyttends to mo"; the shield out over the light beam i The rming elements l-l seated in recesses 13 {and they may be held in place by a frame 15mm] screws 16. The springs 18 are coiled around the pivoty pins or bolts 7 and one end of each spring is secured at 15). while the other end is open to engage one of the frames 8, as best shown in Figs. 2, 5 and (3 of the drawings.

, Many modifications oi our invention may be made, without departing from the spirit of the same and for convenience ot'illustration, we have disclosed two such m0d1tications in Figs. 10 and 11.

In Fig. 10. the-shield 8 is formed of asingle segment and is adapted to intercept the light beam within the lamp 1-, the shield being entirely closed within the lamp and the shield receiving chamber is formed betweer the reflector 21 and the body oi the lamp 1-. v v

In the form shown in Fig. ll. the shield 8 is similarly mounted between the rel'lector 21 and the body 1". The door 2 is hinged in such manner that it will. let down when the shield is retracted and when the shield is moved to cut 01? the light beam. the shield is projected to the outside of said door instead of between the. door 2- and the reflector 31 as in Fig. 10.

, \Ve also desire it understood. that the shield may be composed of any number of sections as may be found convenient in practice and the window parts it may be made of material of any color, either wl'iolly opaque or partly transparei'it. \l'hen colcred glass is used, one lamp may have red -Windo\vs and the other green to give the starboard and port indications.

The further modification shown in Fig".

12 illustrates the shield R. as rcvolublo directly about the lumiuant. When it is in the full line position. shown in. Fig. '12, it acts as the reflector and when in the dotted line. position the light beam is entirely cut ofi'.

From the foregoing description talcrn in connection with tho accmnpauyiug drawings, it is thought that the roniplclcw-nn struction, operation and the many adan- "t-a cs of the invention r-iill be clear o those skilled in the art.
